Perhaps keeping the 24-hour interval but including a new interval (e.g. 18 hours) would find a threshold at which spatial memory using DMI could be extended. Using additional materials for the objects used in the object recognition task could potentially produce significant results. Work in this field provides the potential for the groundwork of research in treating individuals that have deficits/disorders in spatial memory and/or object recognition memory. For example, topographical disorientation has been the disorder given to patients who seem to have selectively lost the ability to find their way within their spatial environment (Aguirre, 1999). Our research could initiate interest in clinical trials to find a medication to help treat this problem. Additionally, research has found that recognition memory is impaired in depressed individuals, so perhaps our research on NE’s effect on object recognition memory could provide a “double-investigation” into treating deficits regarding objection recognition memory as well as mood disorders, such as depression (Brand, Jolles, & Wied,
